人血超氧化物歧化酶两种剂型室温贮存期的估算

Estimatin of the Storage Time of Human Blood Superoxide Dismutase in Two Preparation Forms at the Room Temperature

本文应用加温加速实验法估算两种剂型(冻干和溶液)的人血超氧化物歧化酶(人血SOD)在温室下的贮存期。冻干人血SOD保存90％活力的时间达3年之久,而溶液人血SOD仅为20多小时。经多批样品验证,方法比较可靠。

Estimation of the storage time of human blood superoxide dismutase (hSOD) in two preparation forms (freeze-dried and soluble states) at room temperature by the heating and accelerating experiment was reported. The freeze-dried hSOD had kept its 90% activity for as long as 3 years, while the soluble hSOD could have preserved its 90％ activity for only 20 hours. The methodhad proved to be relatively reliable when used for many series of specimens.
